If you use this derived data in an app, we ask that you provide a link somewhere in your applications to the Open Data Network with a citation that states: "Data for this application was provided by the Open Data Network" where "Open Data Network" links to http://opendatanetwork.com. Where an application has a region specific module, we ask that you add an additional line that states: "Data about REGIONX was provided by the Open Data Network." where REGIONX is an HREF with a name for a geographical region like "Seattle, WA" and the link points to this page URL, e.g. http://opendatanetwork.com/region/1600000US5363000/Seattle_WA

Demographics and Population Datasets Involving Maryland

Household Population Projections for Maryland and the jurisdictions - historical household population 1970-2010; projections out to 2040. Projections prepared by the Maryland Department of Planning, July 2014

This data set is of certified businesses owned and controlled 51% or more by minorities, women, veterans, and individuals with disabilities. The data set is updated daily and is searchable and exportable at this link: http://directory.osd.gss.omb.delaware.gov/index.shtml. The Office of Supplier Diversity's mission is to assist the entire supplier diversity community of minority, women, veteran, service disabled veteran, and individuals with disabilities owned businesses as well as small businesses of a unique size in competing for the provision of commodities, services, and construction to State departments, agencies, authorities, school districts, higher education institutions and all businesses. The Office of Supplier Diversity sits within Government Support Services, a Division of the Office of Management and Budget.

MBE, DBE (Disadvantaged Business Enterprise), SBE (Small Business Enterprise) and ACDBE (Airport Concession Disadvantaged Enterprise) certified businesses are all shown. This dataset contains a list of businesses certified by Minority Business Enterprise (MBE) within the state of Maryland. This program is affiliated with the Maryland Department of Transportation (MDOT) Data are continually updated at MDOT's website for MBE: https://mbe.mdot.maryland.gov/directory/search_select.asp. This dataset was created on Jan. 14 2016 and therefore shows all businesses certified as of that date. The Department of Information Technology (DoIT) will update this dataset using MDOT's source data, at least once per month moving forward. If you have questions about the dataset or data please contact service.desk@maryland.gov.

MTA and partner state, local, and other agencies shall assume no liability for errors, omissions, or inaccuracies in the information provided regardless of how caused; or any decision made or action taken or not taken by any person relying on any information or data furnished within. *** This dataset assesses rail station potential for different forms of transit oriented development (TOD). A key driver of increased transit ridership in Maryland, TOD capitalizes on existing rapid transit infrastructure. The online tool focuses on the MTA’s existing MARC Commuter Rail, Metro Subway, and Central Light Rail lines and includes information specific to each station. The goal of this dataset is to give MTA planning staff, developers, local governments, and transit riders a picture of how each MTA rail station could attract TOD investment. In order to make this assessment, MTA staff gathered data on characteristics that are likely to influence TOD potential. The station-specific data is organized into 6 different categories referring to transit activity; station facilities; parking provision and utilization; bicycle and pedestrian access; and local zoning and land availability around each station. As a publicly shared resource, this dataset can be used by local communities to identify and prioritize area improvements in coordination with the MTA that can help attract investment around rail stations. You can view an interactive version of this dataset at geodata.md.gov/tod. ** Ridership is calculated the following ways: Metro Rail ridership is based on Metro gate exit counts. Light Rail ridership is estimated using a statistical sampling process in line with FTA established guidelines, and approved by the FTA. MARC ridership is calculated using two (2) independent methods: Monthly Line level ridership is estimated using a statistical sampling process in line with FTA established guidelines, and approved by the FTA. This method of ridership calculation is used by the MTA for official reporting purposes to State level and Federal level reporting. Station level ridership is estimated by using person counts completed by the third party vendor. This method of calculation has not been verified by the FTA for statistical reporting and is used for scheduling purposes only. However, because of the granularity of detail, this information is useful for TOD applications. *Please note that the monthly level ridership and the station level ridership are calculated using two (2) independent methods that are not interchangeable and should not be compared for analysis purposes.
